Preventing foot odor is far easier than eliminating it. Foot odor is usually caused by wearing shoes that don’t breathe for far too long a time. The best way to treat your feet in this situation is to wash your feet and change your socks at least once a day. More than once is better, but most people don’t have the time to do it more than once.
Shoes made with vinyl or patent leather are almost waterproof, which means they’re also nearly air-proof. The perspiration from your feet stays trapped inside your shoes while you’re wearing them, keeping your feet, your socks and the insides of the shoes moist (or even wet). If you can avoid wearing these types of shoes, your feet will thank you.
When I was in the military, I hated wearing dress uniforms because I hated the types of shoes I had to wear with them. Those dress shoes caused both me and my wife to treat my feet with extreme care. My wife used to complain that my feet smelled like dried fish, which made her hungry. At first, I didn’t know whether to take it as an insult or a complement.
Foot powder will help cut the odor and absorb some moisture, but not all of it. It works better in shoes that breathe than other types of shoes. I use it while wearing athletic shoes (which is what I wear most of the time). I put it on my feet before I put on my socks and I sprinkle a liberal amount in my shoes. My wife hasn’t complained more than a couple of times since I retired in 1998.
One technique I’ve read about helps to reduce foot odor by causing your feet to perspire less. Stinky feet usually start as sweaty feet (where bacteria thrive), even while wearing flip-flops. I’ve never tried the black tea remedy, but you can read “Home Remedy for Sweaty Feet” if you feel like trying it out.
My wife “forced” me to soak my feet in alum (tawas in Tagalog) and water for a week to kill the bacteria causing my foot odor. She couldn’t stand the smell when I first came home from work. That was back in the late 1980s.
Even though I’ve had issues with foot odor a couple of times since then, it’s never been as bad as it was then. There are very few times when I need to wear shoes more than a couple of hours at a time.
If you have a minor odor problem, charcoal inserts may be enough to take care of it. There are thousands of foot care products being sold over the counter and very few of them are worth using for foot odor.
